Application filed ma lei, 191;, Serial No. 770,925. 'Renewed Februar y 9, 1916.-= 'S e ria1 No. 77,300;

To all whom it may concern:

Be it known that I, LUI GI Vrnzzr, a citizen of the United States and a resident of Jersey City; in the county of Hudson and State of New'Jersey, have invented a new and Improved Fire-Escape, of which the following is a full, clear, and exact description.

chute spaced from the ground and having an auxiliary chute adapted to s'lide'on, the main chute and form a continuation thereof for connecting the main chute with the ground,

means being provided forautomaticaHy releasing the auxiliary chute so that will may descend by gravity to the ground on the opening of a door leading to the main chute, and means also being'provided for sounding an alarm as the auxiliary chute descends.

Additional objects of my invention will appear in the following complete s ecification, in which the preferred form theinvention is disclosed. y

-In the drawings similar charactersof reference indicate corresponding parts in all the views, in which v y a Figure 1 is an elevation of a building provided with my fire escape; showing the auxiliary chute in loweredf'posi'tion. Fig. 2'isa; transverse section of-Flg. 1, showlng the' auxiliary chute n raised positiongF-lg. 3 is a fragn'ientary View showing the construetion of the auxiliary chute; Fig. 41s a transverse sectional view of themain chute; Fig.

5 is a fragmentary view showing 'the imeans'1 by which the auxiliary chute is freed auto-. maticall y on the opening of the doors; and- Fig. 6 is a transverse sectional-yiewyof a modified form of the'main chute.

1 By referring tothe "drawin s itiwill be seen that astandard 5 is profvidechwhich is supported by the horizontal members ,6,"

which are secured tothe building 7; The main spiral chute 8 is supported by the horizontal members 6., there being members 9' which are secured to and depend from'the l'lOlIZOIlttll members 6,thesedepen,ding members 9 being secured to the side of the main chute 8.

Mounted to slide onjthefmain ,spiralchute 8 there is an aux'iliary 'ch'ute 10-, the. auxiliary chute 10 having flanges 11,, which extend over the top of the 'main spiral-chute 8.,

a This auxiliary spiral chute 10 is connected.

My invention relates to fire escapes and it has for its object'to provide a main spiral i alarm.

with a-bearing '12, by members 13 this bearing' 12} being mounted for rotating on the 1n) Secured to'the side;qf the building there is a bracket 14, to which is secured a bell'l5, 1 this bell beingconneeted by a stud 16 with a friction wheel,17,-the friction wheel 17 bearingagainst the outer side of the-aux- Patented Aug. 8, mic.

iliary" chute 19 so that when the auxiliary 1 chute rotates and descends relatively to the mam chute 8,the friction wheel 17 will be rotated to operate; the bell= and sound an Journaled in bearings in the horizontal members 6 there; 'lS-fl, rock shaft 18, an arm 19 being secured; tothe rock shaft 18', this arm 19 being adaptedto be disposed under a fiange20 on the bearing 12, for-supporting the said bearing and the auxiliary spiral chute 10. Therefare also a plurality of arms 21which are Secured to the'rock shaft 18,

links 22 beingarticulated'to the arms 21 and having laterally extendingeyes 23 through Which pass, the links 24, the links 24 having eyes 25 through which the links 22 extend. The links 24: areconnected to doors 26, so -that whenlanyonaof the doors 26 is opened it will draw inwardly the link 24 secured to the door and also thelink 22 connected there with to rock the shaft 18 by means of an armi21. As, the shaft is rocked, the arm 19 r is moved away from thetlange 20 on. the bearings 12,'as shown in the dotted lines in Fig. 5 oflthe drawings, thereby freeing the bearings 12 so that th said. hearings and the auxiliary spiral chutl may descend to con-r nectthe main spiral c utc 8 with the ground, the friction wheel, which is incontapt with the auxiliary spiral chute; so undingan alarm as the auxiliary spiral chute descends; v v a By referring toFigs; 4 and'liof the draw; ings it will be seen thatthe m'ainchute 8 is constructed with a lining of asbestos material 8, which is disposed between-thehneml inner and outer surfaces 8". spiral chute 8 has its top 8 constructed with The main an elongatcdlioml 8 there being ventilating -',windows 8" in the side of the hood 8; It v will be understood that the main spiral chute Sanay be constructed as shownin Fig. 4 of i thedrawings, or, if desired, it may be constructed with its outer sideat the bottom, rounded, as shown in Fig. 6 of the drawingsr p Having thus described my invention I a claim as new and desire to secure by Letters Patent: a

1. In a fire escape a main spiral chute, an auxiliary chute telescoping with the main chute, a standard mounted axially relatively to the main chute, a bearing, mounted on the standard, and members connecting the hearing with the auxiliary chute.

2. In a fire escape a main spiral chute, an auxiliary chute slidably engaging the main chute, a standard mounted axially relatively to the main chute, a bearing, mounted on the standard, members connectmgthe bearing] \Vltli the auxiliary chute, and a member movablerclatively to the bearing for engaging the bearing to support the auxiliary chute.

3. In a fire escape a main spinal chute, an auxiliary chute telescoping with the main chute, a standard mounted axially relatively to the main chute, a hearing mounted on the standard, members connecting the hearing with the auxiliary chute, a friction wheel engaging the auxiliary chute, and an alarm adapted to be operated by the friction wheel. 4. In a fire escape a main spiral chute, an auxiliaryrhute slidably engaging the main chute, a standard mounted axially relatively to the main chute, a bearing mounted on the.

standard, members connecting, the bearing with the auxiliary chute, a rock shaft hav ing an arm for engaging the bearing to support the auxiliary chute, and means to rock the shaft. r

5. In a the escape a main spiral chute, an auxiliary chute slidably engaging the main chute, a standard mounted axially relatively to the main chute, a hearing mounted on the standard, members connecting the hearing \vitlrthe auxiliary"chute, a rock shaft having an arm for engaging the bearing to support the auxiliary chute, a door, and means connecting the door with the shaft for rocking the latter.

auxiliary chute slidably engaging the main (3. In. a lire escape a main spiral chute, an

second-mentioned arm for rocking the shaft when the door is moved in one direction but which permits the shaft to rock relatively to the door.

7. Ina fire escape a main chute, an auxiliary chute slidably engaging the main chute, a rock shaft having means for supporting the auxiliary chute, a secondarm secured to the rock shaft, and telescopic means con necting the door with the second-nyentioned arm for rocking the shaft when the door is moved in one direction, but wlnch permits the shaft to rock relatively to the door.

8. In a fire escape a main chute, an auxiliary chute shdably engaging the mam chute, means for supporting the auxiliary chute relatively to the main chute, a door, and tele- .scopic means connecting the door with the first-mentioned means foroperating the first mentioned means when the. door is moved, but permittingthe first-mentioned means to operate relatiwely to the door,

9. In a fire escape a main chute, an auxiliary chute slidably engaging the main chute,

means for supportin 'the auxiliary chute relatively to the mam chute, a door, and means connecting the door with the firstmentioned means for operating the firstmentioned means, but permitting the firstmentioned means to operate relatively to the door.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
